HU188916B - Sinergetic fungicide compositions for cereals containing derivatives of carbamide acid and ditiocarbamate - Google Patents

Abstract

The invention relates to a synergistic multi-component preparation for the control of the fungal diseases of cereals, in particular for the successful control of burnt mushrooms, mildew and Fusarium spp. The inventive preparation contains as active ingredient a mixture of benzimidazol-2-yl-carbamic acid methyl ester, (8-oxyquinolinate) - (dimethyldithiocarbamate) -Zn complex and (8-oxyquinolinate) - (dimethyldithiocarbamate) -Mn complex. In the prepartate, benzimidazol-2-yl-carbamic acid methyl ester and the metal complexes are preferably present in a weight ratio of 1: 3 to 2: 1. The weight ratio between zinc complex and manganese complex is preferably 1: 1.

Description

The present invention relates to a synergistic composition comprising a carbamic acid derivative and a dithiocarbamate derivative, which is effective in controlling fungal diseases affecting cereals, namely, fungus, powdery mildew and fusarium species. The composition of the present invention contains as active ingredient the benzimidazol-2-ylcarbamic acid methyl ester and the (8-oxoquinolate) - (dimethyldithiocarbamate) zinc-manganese complex in a weight ratio of from 1: 3 to 2: 1. in the composition the weight ratio of the zinc and manganese complexes of (8-oxyquinolate) (dimethyldithiocarbamate) (1: 1).

The most prominent pathogens of cereals (eg wheat, barley) are the following pathogenic fungi:

- infestation by infestation of seed fungi, such as rock thistle (Tilletia foctida) or barley dust pollen, at infestation; (Ustilago nuda); and furazium species (Fusarium spp);

- cereal powdery mildew (eg Erysiphe graminis) is damaged at several stages of development;

- they are damaged by cereal fusariosis (Fusarium graminearum) and rust fungi, such as fungi; the rust (Puccinia glumarum).

Seed germination is used to protect against germ-borne diseases, while spraying with various fungicides against later pests.

In the past, the use of mercury containing agents in the treatment of cereals has been a disadvantage in many respects. Thus, mercury-containing substances are well known for their health-damaging and at the same time accumulative properties, while their use does not provide protection against internal contamination of the seeds.

In the literature, Proc. Br. Insectic, Fungic. Conf. 7th, (1973) pp 127, 301] H. Hampel and F. Löcher first reported the effect of benzimidazol-2-ylcarbamic acid methyl ester (BCM, internationally: Carbendazim) on phytopathogenic fungi; s. It was first described in the US patent as a fungicidal active ingredient in plant protection practice. The protective fungicidal activity of the (8-oxoquinoline) copper complex was first described by Powell in the second half of the forties [Phytopathology, 36, p. 573, 1946].

No. 171,736. Hungarian patent application describes a very favorable fungicidal action of (8-oxyquinolate) - (dimethyldithiocarbamate) mixed ligand metal complexes which, especially when the central metal atom is zinc, manganese, copper, magnesium, iron, cadmium, are always more active than either Complexes of the same ligand containing 8-oxyquinolate, such as dimethyldithiocarbamate. It also states that eg. the effect of a mixture containing 1 part by weight of zinc complex and 1 part by weight of manganese complex is particularly advantageous.

No. 104,686. According to Polish patent application, synergistic effects against Rhizoctouia solani, Phome betae and Ilelminthosporium gramineum fungi were found in a combination containing (8-oxyquinolate) - (dinethyl dithiocarbamate) copper complex and carbendazim in a ratio of 1: 1.

Our experiments with the composition of the present invention have demonstrated that the complex protection against cereal fungi that has been achieved so far unexpectedly outweighs the efficacy of the component 2 protection when using a fungicidal combination of a fungicide component for fungicide seed treatment and cereal stock management. (BCM, benzimidazol-2-ylcarbamic acid methyl ester), while its other component is the mixed ligand zinc and manganese (8-oxyquinolate) (dimethyldithiocarbamate). They show a synergistic effect in the ratio of carbendazim to metal complexes (1: 3) to (2: 1), as demonstrated by experiments. The use of the two metal complexes in an equal weight ratio (1: 1) is most preferred.

Most preferably, the fungicidal composition of the present invention can be used in the form of an aqueous suspension, and its active ingredient is modified to be used for dressing or spray application.

The compositions of the present invention are illustrated by the following examples, which are not to be construed as limiting the scope of the patent.

Example 6

Spray protection of winter wheat against powdery mildew 49 and corneal fusariosis.

For field experiments on 5 hectare plots, we also used NS-Rana 2 wheat seed, which was sown in well-prepared soil on 25 October. 45

Well-hatched and frost-free plants were weeded with a herbicide commonly used in cereal cultivation technology (containing MCPA), aerial spraying, and at the end of the shrubbery (May 5), they were prepared with sulfur-containing F .

Hereafter, the selected plots were treated for the first time at the completion of corneal grafting (May 26) and for the second time on June 10, also by spraying with ΑΝ-2 rigid airplanes. In the treatments, carbendazim (BCM), Dithane Μ-45, (8-oxyquinolate) - (dimethyldithiocarbamate) zinc complex and manganese complex, and the composition according to the invention were both 400 FW (400 g of active ingredient in 60 1000 ml aqueous suspensions). ) as described in Example 2. Spraying was carried out using 501 / ha water and the amount of active ingredient per hectare was 0.25-1.0 kg.

The efficacy against wheat dust mildew was evaluated after the second spraying on June 28, when 100-100 randomly selected productive plants were tested for infection on each plot and the infection index was calculated using the following scale:

- asymptomatic = 5% or less infected,

- 6-10% infection = 11-25% infection = 26-50% infection = 51-75% infection = 76-100% where each infection is healthy and the proportion of infected leaf surface and the average leaf area covered by mycelia of four leaf layers. From the data received, the contamination! index (Fi) was calculated using the following formula:

n where j represents the individual infection scale values, fj represents the frequency of each scale product and n represents the number of plants tested.
